Structure: Private building located in Imola (BO) consisting of No. 2 bodies built in different eras, each with No. 2 floors above ground level and with floors made of latero-concrete.
Foundations: from the information gathered during the inspection, it was found that the original body of the building was underfounded and partly piled while the west area has reinforced concrete foundations.
Disturbance: the lesion lattice (single- and multiple-branch inclined, sub-horizontal and sub-vertical) produced by shear and bending stresses corresponding to asymmetrical deformations, shows shear-flexure type failure with phase of detachment motion, with relative type of motion and classifies the failure as relative terminal differential vertical translation of the southeast face with respect to the main building body. The east edge exhibits terminal anticlinal failure with differential failure relative to the median zone of the southeast face. Vertical and horizontal cracks are present at the interface between the two building bodies.
Soil: From the information gathered during the site survey regarding the soil present at the site, there is a predominantly cohesive soil layer up to a depth of 5-6 m from the bedrock, followed by a high-strength horizon of a granular nature. Clay soils are subject to volumetric shrinkage and contraction due to drying of surface lithotypes and subsequent swelling as a result of seasonal climatic and rainfall patterns. These phenomena are accentuated in the dewatering action exerted by the suction of tree roots in the vicinity of the building, in leaks or dispersions of water or sewage systems, and in the inadequate regulation of downspout drainage water; for the above-mentioned phenomenologies, careful verification and eventual, prompt restoration are recommended.
